Part Interchangeability Between a 1990 4.2 and 1991 4.0
Posted: December 28th, 2020, 11:35 am
I am currently buying parts for my 4.0 stroker build. I would like to know what parts I can take from the 4.2 YJ and use for the 4.0 build
Info on Jeep:
Mopar EFI conversion kit installed
BeCool Rad
-electric fan
- HV alternator
-premier power welder
-ARB air compressor
The rest of the engine bay is stock, from my knowledge.
A big question I have is if the conversion kit wiring harness will work on 4.0
Examples of Info I want to know:
- sensors
-dizzy
- oil pan
-valve cover
-etc
brief info on stroker build:
-4.0 rods
-crank from 4.2
-custom piston
-custom cam
-24lb accel injectors
I don't know the state of a lot of the parts on the 4.0. I so I want to use as much of what I have.
